Mark,
Great results there!
(not sure about the inverted "look" but very nice nevertheless)
Looking at the spiculation layer I'd say you're getting around 0.8A bandwidth.
Well done!

Thanks Ken inverse I know what you mean but it just looks much more interesting visually but these compressed jpeg dont do the originals justice .
How did you work out 0.8A btw
Mark,
When the bandwidth decreases the amount and contrast between the sharper photospheric edge and the spiculation layer decreases...
When you get down around 0.3 to 0.4A (ie generally double stack) the photospheric "edge" disappears and you only get the spiculation, proms etc.
The wider the bandwidth the more prominent the photospheric edge....hence my estimate.
Great images! I have been trying with a ZWO ASI294MC but can't get the exposure anywhere near what you are.
Would you mind sharing your settings??
BTW, I'm using a Celestron Edge 1100HD with a .7 reducer the ASI and a Celestron Sun filter.
Best regards
Ed
As Ken said Ha imaging is different to white light the images look very differrent but in saying that I get around 120fps with the ASI174 which is a mono camera.
